Impact of dispersed PV generation on voltage rise of distribution grid

The paper studies voltage change before and after integration of dispersed PV generations in view of voltage drop, line voltage profiles after integration of single and multiple PV generations are analyzed respectively, one conclusion is gained: line voltage will be raised by the PV generation, and the voltage of one position on line is directly related to all load and PV capacity after this point; The factors affecting voltage are investigated, such as output of PV, PV location, line parameters and load. Finally, two examples are analyzed to verify the study.
